Fields
Public methods
getAccess
public int getAccess ()
Return the access type of the car property.
The access type could be one of the following:
CarPropertyConfig#VEHICLE_PROPERTY_ACCESS_NONECarPropertyConfig#VEHICLE_PROPERTY_ACCESS_READCarPropertyConfig#VEHICLE_PROPERTY_ACCESS_WRITECarPropertyConfig#VEHICLE_PROPERTY_ACCESS_READ_WRITE
| Returns | |
|---|---|
int |
the access type of the car property.
Value is VEHICLE_PROPERTY_ACCESS_NONE, VEHICLE_PROPERTY_ACCESS_READ, VEHICLE_PROPERTY_ACCESS_WRITE, or VEHICLE_PROPERTY_ACCESS_READ_WRITE |
getAreaIds
public int[] getAreaIds ()
| Returns | |
|---|---|
int[] |
Array of areaIds. An AreaID is a combination of one or more areas, and is represented using a bitmask of Area enums. Different AreaTypes may not be mixed in a single AreaID. For instance, a window area cannot be combined with a seat area in an AreaID. Rules for mapping a zoned property to AreaIDs: - A property must be mapped to an array of AreaIDs that are impacted when the property value changes. - Each element in the array must represent an AreaID, in which, the property value can only be changed together in all the areas within an AreaID and never independently. That is, when the property value changes in one of the areas in an AreaID in the array, then it must automatically change in all other areas in the AreaID. - The property value must be independently controllable in any two different AreaIDs in the array. - An area must only appear once in the array of AreaIDs. That is, an area must only be part of a single AreaID in the array. |
getAreaType
public int getAreaType ()
Return the area type of the car property.
The area type could be one of the following:
VehicleAreaType#VEHICLE_AREA_TYPE_GLOBALVehicleAreaType#VEHICLE_AREA_TYPE_WINDOWVehicleAreaType#VEHICLE_AREA_TYPE_SEATVehicleAreaType#VEHICLE_AREA_TYPE_DOORVehicleAreaType#VEHICLE_AREA_TYPE_MIRRORVehicleAreaType#VEHICLE_AREA_TYPE_WHEEL
| Returns | |
|---|---|
int |
the area type of the car property.
Value is VehicleAreaType.VEHICLE_AREA_TYPE_GLOBAL, VehicleAreaType.VEHICLE_AREA_TYPE_WINDOW, VehicleAreaType.VEHICLE_AREA_TYPE_SEAT, VehicleAreaType.VEHICLE_AREA_TYPE_DOOR, VehicleAreaType.VEHICLE_AREA_TYPE_MIRROR, or VehicleAreaType.VEHICLE_AREA_TYPE_WHEEL |
getChangeMode
public int getChangeMode ()
Return the change mode of the car property.
The change mode could be one of the following:
